+      The true type fonts HAN NOM A and HAN NOM B have been developed by Chan
+      Nguyen Do Quoc Bao (Germany), To Minh Tam (USA) and Ni sinh Thien Vien Vien
+      Chieu (Vietnam). Their work got started in 2001, completed in 2003, and
+      publicized in 2005. These two true type fonts can be used with WIN-2000 or
+      WIN-XP and Office XP or Office 2003 to display Han and Nom characters with
+      code points by the Unicode Standard. Two sets of true type fonts are
+      available with high and low resolutions.
